This thesis is concerned with understanding the social representations that impact on how stakeholders understand, value and act in relation to urban consolidation. Urban consolidation is a planning policy that aims to increase the density of dwellings and/ or population within an existing urban area. This policy is a substantial departure from previous urban settlement patterns in the case study city of Brisbane and has encouraged an unprecedented influx of higher density housing. Whilst urban consolidation has attracted significant policy support, it is often staunchly opposed by community groups, generates considerable controversy in scholarship and has often failed to be implemented in cities around the world. Given the wide-spread integration of urban consolidation into planning policies throughout Australia, the US, UK, NZ and parts of Western Europe, it is important to understand how this policy is understood, communicated about and implemented by stakeholders. Research suggests that urban consolidation has failed to achieve the sustainability outcomes it purports to deliver, partially due to a lack of stakeholder will, vested interests and conflicting priorities between different groups.The research methods employed in this thesis include qualitative and quantitative media analysis and Q-methodology to ascertain what social representations about urban consolidation were apparent in the newspaper media and in interviews with planners, developers, residents, peak organisations, architects and local councillors in Brisbane. The media analysis involved Semantic Metaphorical Analysis and Pragmatic Textual Analysis of 440 articles pertaining to urban consolidation published in five Brisbane newspapers between 2007 and 2014. The Q-methodology involved interviews and q-sorting activities with 46 respondents. It interrogated these findings through the lens of Social Representations Theory, a social psychology theory concerned with the creation and circulation of common sense knowledge. The theory features an explicit focus on power, acknowledging the uneven capacity for different groups to promote their own social representations whilst silencing other realities.This thesis provides empirical, methodological, theoretical contributions to urban research. Empirically, this thesis contributes a key insight into the planning, communication, mediation and delivery of urban consolidation and higher density housing. The study revealed that urban consolidation is a complex topic that involves associated issues of land use conflict, regional population management, investment and property, home and housing affordability, neighbourhood change and urban renewal.
